Tell me how backwards this is...

So get this. I go into a ranked solo/duo on my silver smurf because I want to practice my Ryze in bot lane since apparently that's the meta now. Apparently my hardstuck silver support who was assigned support did not agree with my pick. So what does she do? She locks MF and states that she isn't going to play support. Proceeds to go into the game and take CS. Of course I'm not happy about this. But guess who got banned? Riot's instant feedback system is a joke. It literally does nothing to punish the trolls who constantly ruin this community. Please bring back the tribunal.
